I'm more familiar with Germany and Austria. They have federal programs and they've also had provincial programs, so they tie the two. First, they have been very steady. Also, they've been looking at each technology and not putting them all in the same pack. They say, okay, for solar water heating, for example, we'll give so much per square foot, per square metre; for solar space and water heating, we'll give a little more. And all companies involved in the solar business do benefit from the same grants. So that's one of the things they did to make it successful.
Some tried going into carbon credits and some also did go into leasing, making sure that utilities could lease solar collectors, so that overcomes the initial investment barrier. Some went into guaranteed buyback energy programs, as has been the case now in Ontario, for example. They tried that over 10 years ago.
So they've tried all sorts of ways, but recipe number one was stability--commitment and stability, definitely.
